In this paper the experimental tests and the evaluation of the seismic behaviour of the seven simply supported spans concrete bridge crossing the Anapo River (Siracusa, Italy) is proposed. The bridge was not designed according to a seismic code and now is affected by visible damages. An experimental investigation was made in order to evaluate the reliability of the bridge regarding the recent seismic Italian code. The materials were characterized by means of tests on specimens extracted in different locations of the structure. Dynamic tests were done in order to update the finite element model.
